“…The allelochemical isolated from Ficus microcarpa inhibits the growth of Chlorella pyrenoidosa and the primary active fraction was identified as 2-propyl phenol [11]. The allelochemical extracts of invasive plants may inhibit the seed germination and seedling growth of acceptor plants and also exert effects on their antioxidant enzyme activities and malondialdehyde (MDA) contents [12][13][14].…”

Alternanthera philoxeroides is a perennial invasive species worldwide which can greatly affect native ecosystems and agricultural production. Our research studied the allelopathic effects of aqueous extracts of A. philoxeroides on the growth and antioxidant enzyme activities of Zoysia matrella, and isolated and analyzed the dominant allelochemicals in root extracts of A. philoxeroides. The overall allelopathic effects of A. philoxeroides extracts on the growth and antioxidant enzyme activities of Z. matrella were found to be slightly stimulatory (concentrations ≤10 g L -1) and highly inhibitory (≥40 g L -1). Malondialdehyde contents were significantly enhanced with increasing concentrations of A. philoxeroides extracts. The strength of the allelopathic effects of three extracts of A. philoxeroides on Z. matrella followed the order: roots > leaves > stems. The dominant substance was extracted and identified to be ethyl propionate by gas chromatographymass spectrometry (GC-MS). Pot experiment results show that the effects of ethyl propionate on growth and enzyme activities of Z. matrella also ranged from slightly stimulating to highly inhibiting in a similar fashion to the effects of A. philoxeroide extracts on Z. matrella. The overall allelopathic effects of A. philoxeroides on Z. matrella ranged from slightly stimulating to highly inhibiting. The most abundant allelochemical component of root extracts was identified as ethyl propionate, which also exhibited inhibitory effects similar to A. philoxeroides extracts on Z. matrella.

“…Previous studies have indicated that water extracts of donor plants could inhibit the seed germination and seedling growth of receptor plants through the regulation of anti‐oxidase activity, such as POD and CAT in the cells. The growth inhibition of the receptor plant seedlings is probably related to injury after oxidization of the cell membranes with the increase of MDA content . Huang et al .…”

The allelopathic effects of Juniperus rigida litter aqueous extract (LE) on wheat and Pinus tabuliformis were studied, as well as the physiological responses to the extract. High concentration LE (0.10 g Dw/ml) significantly inhibited the seed germination and seedling growth in receptor plants. The chlorophyll content and root activity in the wheat seedlings were reduced significantly across all treatments; however, those were more prominently reduced at high concentration (0.10 g Dw/ml) but received little stimulation at low concentration (0.025 g Dw/ml) in P. tabuliformis. The content of malonaldehyde (MDA) increased with increasing concentrations of LE, except at 0.025 g Dw/ml. Activities of antioxidant enzymes (POD, CAT and SOD) in receptor plants were all significantly inhibited at high concentrations but stimulated at low concentrations. These results demonstrate that the aqueous extract from J. rigida litter has allelopathic potential. Various phenolic compounds were identified in litter aqueous extract and litter ethanol extract by HPLC. The phenolic compound content in the aqueous extract was significantly lower than that in the ethanol extract. Chlorogenic acid and podophyllotoxin were the predominant phenolic compounds in both types of litter extracts. These findings suggest that the seed germination and seedling growth of P. tabuliformis and wheat would be inhibited when planted near large amounts J. rigida litter.

“…Li & Jin (2010) also reported that the stem extracts of Mikania micrantha showed higher inhibitory activity than the leaf extracts. However, the leaves appear to be the most consistent source of chemicals involved in phytotoxicity, producing the greatest inhibitory effects on target species (Souza et al, 2010;Khan et al, 2011).…”

“…Phytotoxic activity depends on the concentration of the extracts and the plant organ from which they were extracted (Li & Jin, 2010). Different plant tissues, such as leaves, stems and roots, can release different amounts of allelochemicals into the surrounding environment (Souza Filho, 2006).…”

-The objective of this study was to evaluate the effect of the ethanolic extract of Serjania lethalis leaves and stems on the diaspore germination and seedling growth of wild poinsettia (Euphorbia heterophylla) and barnyardgrass (Echinochloa crus-galli). The crude ethanolic extract was prepared from 100 g of dry plant material dissolved in 500 ml of ethanol. The extracts were solubilized in a buffer solution containing dimethyl sulfoxide (DMSO) at concentrations of 10.0, 7.5, 5.0 and 2.5 mg mL -1 . The effect of these extracts was compared with herbicide oxyfluorfen in bioassays. The ethanolic extracts of S. lethalis leaves and stems inhibited the germination and seedling growth of barnyardgrass and wild poinsettia in a concentration-dependent manner. The reduction in the root length of E. heterophylla seedlings might be attributed to the reduced elongation of metaxylem cells. The phytotoxicity of the extracts ranged according to the receptor species, and for some variables, the inhibitory effect was similar, and even superior, to that of the commercial herbicide. Thus, S. lethalis extracts might be a promising alternative for sustainable weed management.
